Eaton KRP-C-601SP Fuse - Class L Time-Delay RoHS/CE
Part Number: KRP-C-601SP
Quick Summary
KRP-C-601SP fuse from Eaton Bussmann offers time-delay protection for motor and power distribution circuits up to 600 Vac. In demanding industrial environments, nuisance trips during startup and inrush can erode uptime and inflate maintenance costs. This Class L device features a 601 A rating with a high interrupt capacity, supporting robust protection across motor drives, transformers, and panel feeders, while enabling scalable protection strategies. RoHS compliant and CE marked, it aligns with global safety and environmental standards, reducing compliance risk. The bolted blade end connections simplify field installation, and its non-indicating fuse status supports clean, compact panel design. Together these attributes deliver reliable protection, easier sourcing, and tangible business value through improved uptime and predictable maintenance planning.

Bussmann series KRP-C 601 to 2000A Class L fuse data sheet No. 1008
Feature: Time-delay Class L fuse with current-limiting characteristics. Benefit: minimizes nuisance tripping from inrush, allowing equipment to energize smoothly while preserving protection against faults. Application: motor starters and distribution panels where startup surge is common. Feature: 601 A amperage rating and dual voltage compatibility (600 Vac, 300 Vdc). Benefit: supports high-load industrial circuits and mixed AC/DC environments with a single protective device. Application: main feeders, control panels, and machine centers requiring broad operational flexibility. Feature: High interrupt ratings (300 kA at 600 Vac and 100 kA at 300 Vdc). Benefit: robust fault interruption reduces arc energy and risk during short-circuit events. Application: switchgear and critical power rails in manufacturing lines. Feature: Time-to-trip specification of 4 seconds at 500% rated current. Benefit: provides coordinated protection that limits fault energy without sacrificing short-term reliability. Application: equipment protection where both reliability and selectivity are essential. Feature: Bolted blade end x bolted blade end connection. Benefit: secure, vibration-resistant installation with straightforward field wiring. Application: retrofits and new builds using Bussmann KRP-C family fuses. Feature: RoHS compliant and CE marked. Benefit: regulatory compliance for global deployments. Application: international panel assemblies and OEM equipment with strict environmental and safety requirements. Feature: Non-indicating fuse indicator. Benefit: reduces front-panel clutter while enabling protective relay coordination. Application: space-constrained electrical cabinets and control housings.

FAQs
Yes. The KRP-C-601SP uses bolted blade end connections that are designed for secure, field-friendly mounting within Bussmann KRP-C family holders. Ensure correct torque per manufacturer guidelines and verify mounting clearance in the enclosure to maintain safe operation and reliable cooling.
Key specs include a 601 A amperage rating, voltage ratings of 600 Vac and 300 Vdc, and interrupt ratings of 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc. It also features a time-delay response with a 4-second trip at 500% rated current, balancing inrush tolerance with protective speed.
Yes. Its Class L time-delay design minimizes nuisance trips during motor inrush while delivering current-limiting protection for fault events. This makes it well-suited for motor control centers, drives, and feeders in industrial panels where reliability and selectivity are critical.
The fuse is RoHS compliant and CE marked, supporting regulatory compliance for international deployments. These certifications help meet environmental, health, and safety standards across global manufacturing sites.
Current-limiting capability reduces fault energy and arc exposure, potentially lowering equipment damage and downtime. Time-delay operation accommodates inrush without sacrificing protection, improving uptime and asset life in high-load environments. Easy installation and compatibility also lower maintenance costs during replacements or upgrades.
